I can't even find a datasheet on the thing... but it looks like a
pentode designed for a battery-powered radio.... 1.5V filament, 90V plate.

I am thinking a 1LD5 or 1LC5 might be a reasonable sub, with a base
adaptor.

I think it might be one of them furrin tubes from before the
standardized letter/number numbering system.

Maybe, but I found a bunch of circuits using it out there, like this one:
http://frank.pocnet.net/short/001/1/1SA6.gif which shows an IF stage.

This gives you basing and pinout, some nominal operating voltages, and you
can make a rough guess about transconductance.

It's a octal base, pentode RF amp. The suggested replacement is a 1N5GT.

Many thanks everyone - plenty to go on now!

I have it listed in an old GE Manual if you need any information
on it. Base connections are 6BD, filament 1.4v DC @ 50ma, Ep 90V,
Esg 75V Its an RF Pentode. I found no sub info. Hope this helps.

Any idea who made it? My RCA data books cover the era when it must have been
made, but have no listing.

GE, at least the 1SA6-GT

It's not in my 1955 GE book. Not in a slightly newer Sylvania one either.

I got the tube info from my old Sylvania tube manual. It was up-to-date
through mid-55. The tube was listed in the condensed section, so it was
obsolete at the time it was printed. Don't know who all made it.

The 1N5GT was fully documented, so it was somewhat modern at the time.

My RCA books have the 1N5GT well documented, as you say, but nothing on the
1SA6. They must not have thought it worth stealing. What do you suppose is
the 6th element in the 1SA6?
